Controls charging of Apple Watch and will improve battery life with the outlet which works with IFTTT Webhook. In a word, this App is the semi automatic version of WatchOS standard function 'Optimized Battery Charging'. You can set as you like because of 'non full auto' settings (e.g. In 'Normal' and 'Cut at 80%' mode, the App stops charging at 80% without restarting to 100%). The concept is almost equal to the iOS App 'CharingCharge'. Difference is the way to control the smart plug. This App uses IFTTT Webhook service instead of HomeKit. Take a look at the App's page in the App Store, please. And you can see how this App control charging. https://apps.apple.com/us/app/caringcharge/id1505303275 'Caring' mode suspend charging when reached to the 80% capacity, afterwards restart at the time set. 'Normal' mode simply charge until reaching the capacity set. Difference is if the App restart charging. '80% cut-off Normal Charge Mode' is very suitable for storing the devices as it will damage the battery when fully charged or empty. Connect charger to the smart plug working with the IFTTT Webhook service, please. Lower current (not faster) charger is better in terms of battery damage. The App can't work completely on background due to restriction of WatchOS. So this App can't control charging completely, but execute as ideal as possible. 'Optimized Battery Charging' is recommended to 'Off' not to conflict with this App. (Settings -> Battery -> Battery Health -> ) Two 'Measure' mode is only for measuring the charge speed only and is different from the function with the same name in the iOS app "Caring Charge". ## Key features - Semi-automatic charging control - Custom charging limits (e.g., 80%) - IFTTT Webhook integration - Battery health optimization - Charge speed measurement modes ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/caringcharge-for-watch/id1536092235/reviews.md ### 1/5 — Clueless *2022-02-11* Nothing works on this app how can I get my watch to alarm when it’s charged???? **Developer response:** As stated in the App Store description, this app is not intend to notify you charge completed ! You should read it at least a little making any critical comments, shouldn't you. ### 1/5 — Needs instructions *2021-07-22* I am looking for something that does what this appears to do, but cannot figure out how it's supposed to work. Do you need a proprietary charger of some sort that has a web service? What is this business about watching adds to get credits? Really, if you are taking the time to develop an app, you should take the time to (at least) provide some instructions. If I can figure out how it works, and it does, I'll give it a better review. **Developer response:** Notice-- detailed instruction is now available on Twitter(https://twitter.com/YuCanSoftJp). Check it please. Should you have any questions or concerns, please do not hesitate to contact me. Thank you for your attention to my app. I think too, it is better to be provided more instruction for the person unfamiliar with IoT (Internet of Things). I will write it in Twitter. When completed, I will notice. In briefly, you need to buy the smart plug which works with the IFTTT webhook service and register it on the IFTTT web site. Accessing unique url provided by IFTTT, my App controls smart plug . So need to set smart plug between the charger and AC outlet and input the url to the iPhone App. Ads help support my business, but you may use my App daily almost without iPhone App (i.e. without watching ads). So credit which you can get by watching ad is required to start charging from Apple Watch. ## Frequently asked questions about CaringCharge for Watch ### Does CaringCharge for Watch have ads?
